METHOD OF MODIFYING RUBBER MIXES AND RUBBERS |
摘要 |
FIELD: chemistry. ^ SUBSTANCE: invention relates to the method of modifying general- and special-purpose rubber mixes and rubbers built around high-molecular carbon-chain polymers. Modification of rubber mixes and rubbers is carried out with the help of low-molecular unsaturated polyketones incorporating carbonyl groups and double C=C bonds statistically distributed over the polymeric chain. Modification is effected by adding 0.5 to 50 wt % of low-molecular unsaturated polyketones to the rubber mix, the aforesaid percentage being related to the total content of high-molecular polymer and low-molecular unsaturated polyketone. Note that unsaturated polyketones used for modification contain 0.1 to 16 wt % of oxygen in the form of carbonyl groups and feature a number average molecular weight of 500 to 100000. ^ EFFECT: improved of technical characteristics of rubber mixes and increased strength characteristics of rubbers produced by vulcanisation of such rubber mixes. ^ 7 cl, 11 tbl, 8 ex
